Say I have a bag of ice cubes. Its mass is 25 grams. When it changes from solid to liquid, will its mass still be 25 grams?
Will a change in state of an object affect its mass?

There are some things that you have to learn to trust even though we can't prove them. All such items are called "axioms" except in geometry where they are called "postulates".
1. It is possible to know something. If it were not so then we would have no reason to study.
2. The universe is governed by immutable laws. If it were not so then it is governed by magic and we should have to learn magic.
3. All laws of the universe act the same in all locations and in all cases. If it is not so then we must discover a law that governs the variations.
Other laws are taught in classes dealing specifically with them, such as basic electronics, basic physics, and others. You need to learn these basic laws for your subject, and learn to trust them. Mass is a basic definition that does not depend on temperature, position, or state. There are some variations, such as nuclear bombs, but you don't need to worry about those advanced topics. You can go to wikipedia.org and type any word into the search box to get access to all available knowledge. You can also go to physics.nist.gov/cuu/Units/index.html to see the definitions for international units.
